The Base Layer: Patagonia Capilene Tank & Briefs

What's the last thing you want to feel as you edge your way up a face climb? Your base layers creeping into places you wish they wouldn't. Patagonia's Capilene base layers aim to solve that problem, because they were designed to be the least intrusive article of clothing on your body. The Capilene briefs and tank are seamless and streamlined, giving support and warmth with a lightweight, ultrasoft nylon/spandex mix that's moisture-wicking, stretchy, and quick to dry. Both of our choices get the details right: The tank is supportive without wires and the straps lay close to the body, and the brief's waistband stays put, which means no bunching, no chafing, no rolling over, and best of all, no tugging—so you can keep your hands on the rock.
